Virtual Private Gateway – VGW The introduction of the VGW introduced the ability to let multiple VPCs, in the same region, on the same account, share a Direct Connect. Prior to this, you’d need a Direct Connect Private Virtual Interface (VIF) for each VPC, establishing a 1:1 correlation, which didn’t scale well both in terms of cost and administrative overhead.  VGW became a solution that reduced the expense of requiring new Direct Connect circuits for each VPC as long as both VPCs were in the same region, on the same account. This construct can be used with either Direct Connect or the Site-to-Site VPN.
